The total production and consumption of ozone depleting substances in EEA member countries has decreased significantly since the Montreal Protocol was signed in 1987, nowadays it is practically zero. Globally, the implementation of the Montreal Protocol has led to a decrease in the atmospheric burden of ozone-depleting substances (ODSs) in the lower atmosphere and in the stratosphere. Many ODSs are also potent greenhouse gases. The phasing out of ODS under the Montreal Protocol has reduced global greenhouse gas emissions by an amount 5 to 6 times larger than the UNFCCC's Kyoto Protocol target for the first commitment period, 2008-2012.
